A year ago it seemed like Robert Downey Jr. was slowly exiting the Marvel Cinematic Universe. Now it seems he wants back in and more to him. Reports show that Downey Jr. with Marvel Studios President Kevin Feige have negotiated a way for him to have a hefty presence in "Captain America 3". A role that was initially being written for him in a smaller capacity.

This script restructuring has led to the people at Marvel to plan ahead for the comic book storyline Civil War, where Cap and Iron Man go head to head over the Superhero Registration Act to be the main plot for the "Avengers 3".

However this storyline trajectory maybe a little bit too soon to attempt, meanwhile Marvel hasn't finished introducing its new TV characters in Daredevil, Luke Cage and Jessica Jones and with key players such as Spidey, FF and even the Thunderbolts missing in action from the Marvel Cinematic Universe. While Civil War might be a great storyline that could provide great action set pieces and character confrontations. Its ramifications are too big for such a young universe to possibly cope with.
